Bent T-bar with tube which slips over the end of a standard pump handle. A screw keeps it in place
Prototype of adapted pump handle being trialled in conjunction with a concrete seat
P-handle with a hollow pipe that slides over the end of India MK II pump handle and is kept in place with screws
Suitable for: Users with limited strength or grip.


Construction Advantages Disadvantages Improvements / variations Cost / labour
Bent T-bar with tube which slips over the end of a standard pump handle. A screw keeps it in place
  • Provides extra leverage which makes pumping easier
  • Provides choice of position to operate handle from: front or side
Might invalidate pump warranty Medium
Prototype of adapted pump handle being trialled in conjunction with a concrete seat
  • Can be operated from either side or the front, according to user preference
  • Seat is located to one side, so as not to obstruct standing users
  • Much heavier than standard handle
  • Handle not liked by community who feared children could be hit on the head
Based on testing with local users, this handle has been rejected in favour of the P-handle below (but is included for interest). High
P-handle with a hollow pipe that slides over the end of India MK II pump handle and is kept in place with screws
  • A completely new handle is not needed
  • Local artisans can be trained to make P-handle
  • Can be operated from the side or front according to user preference
  • India Mk II handles vary, so artisans must be trained to tailor adaptation to handle dimensions
  • Not applicable to other handpumps, e.g. Afridev
